Abstract

PURPOSE: A specific nonhalogen foaming agent and a specific stabilizer are added to polyisocyanate and polyol and their reaction is effected to markedly improve the light resistance and deterioration on the surface of the titled resin with no use of specific substances.
CONSTITUTION: A volatile nonhalogen compound as a foaming agent, an antioxidant as a stabilizer, preferably 2, 6-di-t-butyl-r-methylphenol, an ultraviolet absorber, preferably a benzotriazole and/or a hydrolysis inhibitor are added to polyisocyanate and polyol and they are subjected to the reaction in a tightly closed vessel by the reaction injection method to produce the objective resin. The foaming agent is a saturated hydrocarbon boiling at 20W100°C such as pentane and/or an oxygencontaining hydrocarbon bearing no active hydrogens such as acetone. Two or more kinds of stabilizers are preferably added.
